IMPROVEMENT IN HARVESTER-CUTTERS.

Specicatioaformt'ng part of Letters Patent No. 104,773, dated June 28, 1870.

" To Lall whom it may concern:

Be it known that I, FRANCIS E. ROGERS, of Paw Paw, in the county of Lee and State of Illinois, have invented a new and useful Improvement in Mowing and Reaping Machines g' and I do hereby declare that the following is full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication. i

My invention relates to that class oi' mowers and reapers wherein theknives are carried on an endless chain; and consists in certain improvements thereon, to be more particularly l Specified hereinafter.

Figurel represents a plan view 'of my improved sickle device. Fig. 2 represents a section ofthe same, taken on the line x x of Fig. 1. Fig. V3 represents an elevation of one of the chain-sections. Fig. 4 represents a plan view of one of the sickle-sections or cutters; Fig. 5 represents an elevation Of Oneof the chainsection connecting-links. Fig. 6 represents a view of a connecting-pin. f

Similar letters of reference indicate corre' sponding parts.

I propose to connect the cutters A to an endless chain Or carrier having a continuous motion over chain-carrying Wheels B, at cach end of thecutter-'supportin g bar, one of which is a driver vand arranged to be rotated from any suitable revolving wheels,'deriving motion from the truck-wheels. The llower part of the chain moves along the upper surface of the cutter-supporting bar C, so arranged that the cutting-edgesof the cutters project in advance of it, and the upper part ofthe chain is made to turn downward after passing over the pulley by a guide-roller, D, so that the cutters thereof will be carried' alongl the upper faces of those below, and 4at the other end, where the chain rises to pass over the lother pulley, y

a similar guide-pulley, E, is placed, and between. these a guidefplate, F.

As the cutters have a continuous forward movemenathey are provided with only one v cutting-edge, running diagonally from side to side, which, going out at the bottom and back at the top,act`together to make a shear cut. These cutters are fitted by dovetailin g to chain-sections G, slotted and bored at Vthe ends for fitting the connecting-links H, which tit into the slots in the ends ofthe said links, and are connected by pins K. m,

These pins are larger at each end than at the center, and the pin-holes in the links are elongated and enlarged at the ends, near the center of said links, so that ythe pins can neither pass in or out, except when the enlarged parts of the holes in the links are adjusted to the proper position relatively to the holes in the sections, and this adjustment can only be done when the links stand at right angles to the sections, so that a ready means of connection or disconnection of the sections is provided,

which cannot become disconnected when the chain is in place on the chain-wheels, the plO- f jecting ends of the links fitting into the slots Oi' the sections.

The sections G of the chain are grooved Or curvedin the back, as shown at L, to permit them to pass under the rollers D E.

vThis method of connecting the links avoids The chain-sections G, links I, pins K, and

cutters A, all combined and arranged substantially as specified.
